Purpose: The purpose of this study was to explore experiences among undergraduate nursing students in a high-fidelity simulation education course for a semester. Method: The participants in this study were 10 nursing students in the senior classes and volunteers. Data collection was conducted using a focus group interview for 100 minutes, which was recorded on video tape. Transcribed data was analyzed through qualitative content analysis. Result: The results of this study were deduced as 4 codes and 22 themes. Study participants reported experiences due to the simulation method itself, interaction among peer group and personal experiences during high-fidelity simulation education. Additionally, experiences related to clinical application were examined. The participants indicated positive outcomes such as developing clinical judgment skills and confidence. Conclusion: Overall, the results of this study supported the usability and effectiveness of a high-fidelity simulation education method in undergraduate nursing curriculum.

Retention of CPR knowledge was assessed in a group of 86 police officers who participated in first aid and emergency rescue program on February, 2001 and 3 months later. Police officers were taken written test about CPR knowledge by American Heart Association Guidelines 2000 and competence level. Data were analyzed by Frequency, Percentage, Mean, paired t-test using SPSS program. The results for this study were as follows ; 1. In the post-test, the highest question was a rechecking time of circulation sign(98.8%), the lowest was a check for signs of circulation(17.4%), in 3months later, the highest question was a chest compression(94.2%), the lowest was a check for signs of circulation(1.2%), and a retention of CPR knowledge was a 71.7%. In 3months later, knowledge level was decreased compared to that of post-test(t=-9.09, p=.000). 2. In 3months later, the competence level was decreased compared to that of post-test(t=3.09, p=.003).

This study was conducted to identify an initial fire station experience of EMT students, so to better understand their' practice experience in fire station. The subjects were 28 EMT students of C department of Emergency Medical technology in C city, who were demonstrating at the fire station in C city. This study was approached by phenomenological method, collected data were analyzed by Colaizzi's method, the results were as a follows. From the protocol, 201 significant statements were organized into 93 formulated meanings. From the formulated meanings, 30 themes were identified, organized into 16 theme clusters, and then 7 categories. EMT students got experienced 'tension' in resulting from new training situation and at the field practice, 'comport and gratitude', in feeling of identity and a bond sympathy with senior EMT, in training environment and heartfelt care, 'stress' from lack of knowledge and skill, difficulties in field practice for 24 hours, in dealing with making interpersonal relationship with patient and staffs and from the insufficiency of instruction, 'confidence feeling' from the participation of field treatment, in improving of learning, in self-esteem of EMT job, 'confusing feeling' of conflict of the path in work, 'disappointment and doubt' by the discrepancy between learning and actuality, and disappointment of actuality, 'feeling of lack' based on the passive attitude. The results of this study are to use as basic data for students attending fire station experience for the first time.

Purpose: The purpose of this study is to explore the subjective experiences of relapse and treatment among the alcoholics. Methods: Phenomenological methodology was used for the study. Participants were seven people with inpatient alcoholics at the alcohol treatment center at K hospital in K province. Data were collected via in-depth interviews from March to September, 2012 and analyzed using Colazzi's framework. Results: Six themes and seventeen meanings were formulated for the relapse and treatment experiences of participants with alcoholism. Six themes were 'Lack of true insight', 'Lack of strength to live a life', 'Unable to overcome an urge to drink', 'Being drawn away from others', 'Falling into the powerlessness and despair', and 'Being foothold of self-growth'.

Bacillus sp. strain K-l, which produces a strong fibrinolytic enzyme, was isolated from chongkukjang, a traditional Korean fermented soybean paste. The fibrinolytic enzyme was purified from chongkukjang base by using ammonium sulfate fractionation and chromatographic techniques. Purified enzyme, CK K-1 was demonstrated to be homogeneous by SDS-PAGE and isoelectric focusing electrophoresis, and has molecular mass of a 12.4 kDa and a pI of 8.0. The optimal reaction pH value and temperature were 8.0 and $40^{\circ}C$, respectively. Phenyl-methyl-sulfonyl-fluoride (PMSF; serine protease inhibitor), ethylene-diamine-tetra-acetic acid (EDTA; metallo protease inhibitor), copper ion, ferric ion and lead ion inhibited the enzyme activity. These results indicated that the fibrinolytic enzyme is a metallo-serine protease and different from nattokinase and chongkukjangkinase.

Yellow dye-stuffs in natural plant were extracted from a gardenia, saffron, safflower, amur tree and pagoda. And then they were used to color Korean handmade paper(Hanji) on using a mordant. The results of the degree of discoloration are as follows. 1. As for a gardenia(Gardenia jasminodes Ellis for. grandiflora Makino), the effects of coloring were outstanding in the acid area. But for the preservation, it might be desirable that used a lye in a dye-stuff obtained at $40{\pm}5^{\circ}C$. 2. As for saffron(Curcuma longa L.), when used alum as a mordant, it was colored to a medium yellow color with green color. But easily discolorated and was not desirable. And, it didn't fit in a dye-stuff of Hanji. 3. For safflower(Carthamus tinctorius L.), when pH was in the low acid it was colored to the cleaner yellow color. It was the distinction of discoloration that the degree of brightness's increase was low. 4. For amur cork-tree(Phellodendron amurense Rupr.), the effects of yellow coloring were great in the areas of acidity and alkali. But, when used alum, the degree of the discoloration was high and was not effective. 5. For pagoda tree(Styphnolobium Japonica L.), using a calcium hydroxide as a mordant, enabled the more than average yellow to be gained. The degree of discoloration was good.

Objectives : The aim of this study was to evaluate the relationship between the hand washing management and tooth brushing frequency. Methods : The subjects in this study were 7,285 adults who were selected from the third-year(2009) raw data of the fourth national health & nutrition survey. Results : The mean frequency of daily toothbrushing was 3.35. Increases the frequency of both toothbrushing and hand washing with higher grade class. The higher the tooth brushing frequency, the intention of hand washing management at school and home was more increased.

Purpose : The purpose of the present study is to analyze the accuracy and fatigue felt by lay persons receiving CPR training when they perform hands only CPR (HOCPR) and traditional CPR (TCPR). The performance of CPR data will provide the criteria of dispatcher guidelines for the general public. Methods : For 2 minutes duration, HOCPR was conducted by 51 subjects and TCPR was conducted by 48 subjects. The accuracy measurement of chest compressions was based on the 2010 AHA guideline; the subjective fatigue level in before and after experiment was measured by a self-administered questionnaire. Results : There were no significant differences between the average depth, chest compression depth and chest compression location in terms of chest compression accuracy. However, there were significant differences between the two experimental groups in the accuracies for average speed and chest compression speed. The subjective fatigue level showed no significant difference. Conclusion : The experimental group performing HOCPR showed more accurate compression speed and lower fatigue level. These results suggested that HOCPR would be more effective in training the lay persons in accordance with the voice-instructed CPR.

The essential oil of Swertia chirata Buch.-Ham. was extracted by solvent extraction (n-pentane:diethylether, 1:1) method using simultaneous distillation-extraction (SDE) apparatus and analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of essential oil obtained from S. chirata was 236.47 mg/kg. Seventy seven compounds of the essential oil belonging to chemical classes of acid (4), alcohol (21), aldehyde (15), ester (3), furan (3), hydrocarbon (7), ketone (17) and miscellaneous (7) were tentatively identified. The major volatile compounds ranged in content order were as follows: undecanoic acid (28.63%), 2-buten-2-one (20.42%), camphor (18.40%), 2-heptadecanone (14.72%), and cedrol (13.07%).
